    Silica particles were obtained by the Stöber method, in order to analyze the feasibility of creating a pedagogical guide that allows apprentices to apply knowledge about nanotechnology for the functionalization of textiles. The assembly of the reactor was carried out with the instruments and equipment of the laboratory of the Textile and Leather Manufacturing Center, and, through a video, the reaction step by step was documented.According to the factorial experimental design, nine experiments were carried out, with two control variables: reaction time with the catalyst (0.5 hours, 1 hour and 2 hours) and quantity of the catalyst NH4OH at 30% (15%, 20% and 25 %). The samples were analyzed by SEM microscopy, finding that, with 1 hour and 20% of the catalyst, more uniform and smaller particles were obtained, while with 0.5 hours and 2 hours, the particles were more amorphous. Through the nanosizer particle size analyzer, it was obtained that the average is 349.5nm with a high dispersion. The product obtained has potential for use in fabrics as a waterproofing, self-cleaning and anti-puncture agent, since the particle size is small enough to be incorporated into thick fibers.It was concluded that during the process, it is essential to maintain constant agitation at 190 RPM and increase to a minimum of 400 RPM in the addition of the catalyst. It is recommended to analyze how the order of addition of the reagents and the synthesis of particles at ambient conditions influence the final size.Se realizó la obtención de partículas de sílice por el método Stöber, con el fin de analizar la viabilidad de crear una guía pedagógica, que permita a los aprendices aplicar conocimientos sobre nanotecnología para la funcionalización de textiles.

Las muestras se analizaron mediante microscopía SEM, encontrando que, con 1 hora y 20% del catalizador se obtuvieron partículas más uniformes y de menor tamaño, mientras que con 0.5 horas y 2 horas, las partículas resultaron más amorfas. A través del analizador de tamaño de partículas nanosizer, se obtuvo que el promedio es de 349,5nm con una alta dispersión. El producto obtenido tiene un potencial de uso en tejidos como impermeabilizante, autolimpiante y antipunzón, ya que el tamaño de partícula es lo suficientemente pequeño para incorporarse dentro de fibras gruesas.Se concluyó que durante el proceso, es indispensable mantener la agitación constante a 190RPM y aumentar a mínimo 400RPM en la adición del catalizador. Se recomienda analizar cómo influye el orden adición de los reactivos y la síntesis de partículas a condiciones ambiente en el tamaño final

    Skin and soft tissue infections (SSTI) represent the third leading cause of infectious disease consultation for medical services after respiratory and urinary tract infections. This document generates a clinical practice guideline with 38 recommendations based on evidence, graduated under the SIGN system for the diagnosis and treatment for SSTI infections in adult patients in Colombia, following a process of adaptation of guidelines published, and the systematic search and synthesis of literature for the updating of scientific evidence. In addition, a consensus of experts was made for the evaluation of the potential barriers for the implementation of the recommendations and the evaluation of the degree of recommendation in the local context. © 2019 Asociacion Colombiana de Infectologia.

    Experiencias de profesores en su quehacer en los distintos ambientes de aprendizaje presenciales y a distancia.Para el Centro de Excelencia Docente aeiou constituye un honor presentar la publicación del Tercer Encuentro de Prácticas Pedagógicas Innovadoras en el que se destacan cuarenta trabajos de profesores de UNIMINUTO provenientes de diferentes sedes. Con este encuentro son ya tres que bajo la dirección de aeiou los profesores han compartido su quehacer en los distintos ambientes de aprendizaje presenciales y a distancia. Cada año el Centro de Excelencia Docente invita a los profesores a participar en este evento, para el 2108 además de la inscripción voluntaria por parte de cada profesor, se invitó al estudiantado a que postularan a sus profesores que consideraban eran innovadores y creativos en el cumplimiento de su función docente y se obtuvo una respuesta importante por parte de los estudiantes, que para algunos profesores resultó sorpresiva porque quizás no habían considerado que el trabajo que hacían en su ambiente de aprendizaje era diferente, fuera de lo común. Luego de una evaluación de jurados nacionales e internacionales de las prácticas presentadas y de la realización del evento, que tuvo como novedad hacerlo de forma simultánea en cuatro sedes donde UNIMINUTO tiene presencia: Buga, Ibagué, Pereira y Bogotá, se comparte la presente publicación para tener como referencia y evidencia el trabajo que los profesores hacen a diario

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    El efecto de la deshidratación de zanahorias sobre sus propiedades físico-químicas utilizando un proceso simultaneo de ósmosis y secado convectivo

    En este trabajo se modificaron las características naturales de la zanahoria (Daucus carota L.) aplicando de forma consecutiva procesos de deshidratación osmótica y secado por aire caliente. En particular, se estudió el efecto de una solución hipertónica de sacarosa concentrada a 50-60% p/p y una temperatura de secado de 60 oc, sobre las propiedades físicas y químicas del vegetal. Las muestras deshidratadas se analizaron comparativamente frente al alimento en fresco mediante la determinación de la humedad, actividad de agua, sólidos solubles,PH,porcentaje de acidez, color,resistencia a la compresión y contenido de carotenos. Se encontró que el proceso de deshidratación combinado promueve una reducción en el peso de la zanahoria mayor al 70%, actividad de agua por debajo de 0,4, acidez cercana al2% y sólidos solubles entre 28 y 35 o Bx, sin modificar significativamente el color natural del alimento ni su contenido de carotenos (aprox.60 mg/Kg)
